This scale Twin 14 inch/45 caliber Gun Turret set of two turrets is designed for models of New York class battleships USS New York BB-34 and USS Texas BB-35. These ships had five twin turrets. This version represents the two superfiring turrets located on tall barbettes well above the main deck with small rangerfinders, Turrets Numbers 2 and 4. These 3D-printed turrets are intended as direct replacements for the Trumpeter kits' turrets which are incorrectly shaped.

From Wikipedia: "The 14"/45 caliber gun, (technically naval rifles) whose variations were known initially as the Mark 1, 2, 3, and 5, and later as the Mark 8, 9, 10, and 12, were the first 14-inch guns to be employed with the United States Navy, and were for over a year the most powerful naval ordnance afloat. They were installed aboard the United States Navy's New York-class, Nevada-class, and Pennsylvania-classbattleships as the primary armament for each battleship in the class. The gun also saw service in the British Royal Navy, where it was designated the BL 14 inch gun Mk II.

"The design of the 14"/45 caliber dates to about 1910, and they entered service in 1914 aboard USS New York. At the time of their introduction they were intended to fire 1400 lb armor-piercing (AP) projectiles containing a bursting charge of explosive D. Propellant charge was four silk bags of smokeless powder, each of which weighed 105 lb. At a 15 degree angle, the guns could fire a shell out to 23,000 yards. Each individual gun weighed 140,670 lbs without the breech and measured 642.5 inches in length.

Due to the attack on Pearl Harbor, both Oklahoma and Arizona never fired their main batteries in anger. However, the 14"/45 caliber guns salvaged from the number 2 turret aboard Arizona were removed and installed aboard Nevada in the fall of 1944. The aft turrets from Arizona (numbers 3 and 4) were moved to become United States ArmyCoast Artillery Corps Battery Arizona on the west coast of Oahu and Battery Pennsylvania on Mokapu Point.

"Eight US-Navy standard 14-inch 45 caliber guns, complete with mountings, built by Bethlehem Steel, were supplied to the United Kingdom in World War I. They were mounted on Abercrombie-classmonitors under the British service designation BL 14 inch gun Mk II."
